Product Summary

The ET9600-LF is a line driver. It is similar to the four channel 26ET31, with the added feature of providing an internal LED drive. The ET9600-LF is biased so that the base of the LED drive transistor (shown) is held at 2.5V. To set the LED current, connect a resistor from RSET to ground. For more information on LED drive, see application note APP-D2. Voltage connected to the VCC pin is regulated for use by logic functions within the chip, while the output drivers run off this voltage without modification. The ET9600-LF marking (see photo) includes the suffix SCP to denote that this version has short circuit protection. Applications are (1)Optical encoders; (2)Industrial controls.
